+# Sequence Runner
+
+---
+
+## 🚀 Overview
+
+**Sequence Runner** is an very easy-to-use and elegant app for making sequences of `*.exe`, managing and running them. Build with **C++** and **Slint**.

+
+### Why should I use it? 
+
+Imagine you enjoy playing Severed Steel with music while recording your gameplay. Basicly you'd **open Steam**, **start Severed Steel**, then **start OBS Studio**, then **open AppleMusic**. And what if you play like that every day? 
+
+And now imagine that you can launch all of these with just **one click**. Sound cool, right?
+
+---
+
+## 📦 Installation
+
+1. Download from the lates Release `SequenceStarter.zip`
+2. Unzip it and run `Sequence_Starter.exe`

+
+## 🤔 How to use it?
+

+
+### ✅ Add new sequence
+
+1. Select **Create** tab(by default it's already selected).
+2. Press **Add element** to add `.exe` to your sequence. You can add as many as you want. Press **Remove element** to remove last element.
+3. In **Sequence name** write name for your sequence.
+
+After all these actions, **Create** tab will look smth like that:

+
+> `SeveredSteel.exe` and `AppleMusic.exe` are elements of sequence "Vibe".
+
+4. Press **Create sequence**.
+
+> [!NOTE]
+> It will create `sequences.json`, where will be stored all your sequences. If you will delete all sequences - `sequences.json` will be deleted. It's normal behaviour.
+
+

+
+### 👟 Run sequence
+

+2. Press **Start sequence**.
+
+> If you forgot which elements you added in selected sequence, press **Show sequence files**. If you want to remove sequence, press **Remove sequence**.
